Oh my goodness. I couldn't even install Vegas Pro 13 because it can never, ever finish downloading the Microsoft .NET 4.0 Framework, and now as soon as I double click Vegas Pro 11 to load I get Sony's "Vegas Pro has stopped working" window. Here's the error message.

I can't even open Vegas Pro 11. I tried uninstalling and reinstalling Pro 11 and I have the same problem. This is driving me insane.
